A refreshingly cool air mass pushed into the Mid-Atlantic region just in time for the Father’s Day weekend and it’ll remain quite comfortable today as we begin a new work week. The upper-level flow remains generally in a northwesterly direction across the northeastern states with high pressure ridging centered over the middle of the nation and as long as this is the case, sustained heat will be difficult to attain in this region. As far as precipitation is concerned, after a rain-free day today, the chances for showers will rise some later tomorrow. Then there appears to be a real good chance of chance of showers and thunderstorms later Wednesday into Wednesday night and some of this rain can be heavy. Later in the week, we’ll have to watch out for the movement of a cut-off low pressure area over the western Atlantic Ocean which could change the current outlook for generally dry conditions around here.

A couple of cold fronts will usher in a spectacular air mass for this time of year just in time for the Father’s Day weekend. An initial cold front passed through the area last night and the arrival of a second front later today can spark an isolated shower or thunderstorm. Strong high pressure will then take control of the weather for the weekend…a system that had its origins way up in northern Canada providing us with very comfortable temperatures and humidity levels. There will be a stiff NW wind on both weekend days with gusts to 30 mph possible. Elsewhere, intense heat will continue to affect the region from the south-central states-to-the Southeast US over the next several days and some of this hot air will try to make an advance into the Mid-Atlantic region by the middle of next week.

A couple of cold fronts will usher in a spectacular air mass for this time of year to the Mid-Atlantic/Northeast US/Great Lakes just in time for the upcoming Father’s Day weekend. There will be some active weather, however, before we get to that point with scattered showers and strong thunderstorms early today and likely again this evening associated with an initial cold front. There can be another shower or thunderstorm on Friday associated with the arrival of a secondary cold front. Strong high pressure will then take control of the weather for the weekend…a system that had its origins way up in northern Canada. Elsewhere, intense heat will continue to affect the region from the south-central states-to-the Midwest-to-the Southeast US over the next several days and some of this hot air will try to make an advance into the Mid-Atlantic region by the middle of next week.

A couple of cold fronts will usher in a spectacular air mass for this time of year to the Mid-Atlantic/Northeast US/Great Lakes just in time for the upcoming Father’s Day weekend. There will be some active weather, however, before we get to that point with the threat of showers and strong thunderstorms from late tonight into early tomorrow morning and then again on Thursday evening in association with an initial cold frontal system. In addition, there can be another shower or thunderstorm on Friday as a secondary cold front arrives in the Mid-Atlantic region. Strong high pressure will then take control of the weather for the weekend…a system that had its origins up in northern Canada.

The timing of the next cold front could turn out to be perfect as it likely clears the way for a very nice June weekend in the Mid-Atlantic region featuring very comfortable temperatures and humidity levels. It will be quite breezy, however, on both weekend days. The cold front will generate some shower activity in the area anytime from late tonight into tomorrow night and there can be a couple of strong thunderstorms mixed in as well. High pressure from Canada will drop to the Great Lakes by the weekend and will anchor a cooler-than-normal air mass for the region on both Saturday and Sunday. Elsewhere, the next several days will feature some very hot weather in the Midwest and Southeast US and some of this air will try to make it into the Mid-Atlantic region by the middle of next week.

Today has been an active weather day in the Mid-Atlantic region and there will be more shower and thunderstorm activity later in the week with the arrival of the next cold front. The timing of the next cold front could turn out to be perfect as it likely clears the way for a very nice June weekend in the Mid-Atlantic region with very comfortable temperatures for this time of year. Looking ahead, an intense heat wave is likely to develop during the first half of next week from the nation’s mid-section to the southeastern states and some of this heat may expand to the Mid-Atlantic region by mid-week.

An area of showers and thunderstorms that developed late yesterday over the Upper Midwest dropped southeast across the Great Lakes in the overnight hours and will impact part of the Mid-Atlantic region this morning. High pressure will build back into the area later today and it’ll stay quite warm into the latter part of the week. A cold front should push through the area by the end of the week paving the way for more comfortable temperatures this weekend.

A strong ridge of high pressure in the upper part of the atmosphere has formed over the nation’s mid-section and the Mid-Atlantic region is on the outer periphery of this large-scale system. As such, winds aloft in this part of the nation are flowing from northwest-to-southeast and often times this time of year, the outer perimeter of strong high pressure ridging is an active zone with strong thunderstorm activity. Indeed, this “ring of fire” around the high pressure system is very active today with a complex of thunderstorms now exploding over the Upper Midwest. This “mesoscale convective system” (MCS) as it is referred to by meteorologists is likely to drop southeastward in the overnight hours and reach somewhere in the Mid-Atlantic region on Tuesday morning. Latest trends and observations suggest the worst of the MCS could focus on DC, Maryland, Virginia and the Delmarva Peninsula, but stay on guard in Philly.

After an unsettled weekend featuring occasional showers and thunderstorms, it’ll turn warmer this week, but with continued unsettled conditions and chances of showers and thunderstorms. Strong high pressure ridging has set up from the middle of the nation to the southeastern states providing that part of the country with some very hot weather. The Northeast US is on the outer perimeter of this upper-level ridge and it is an active region to be in with the possibility of showers and storms moving from NW-to-SE in coming days to the northeastern states. In fact, we’ll have to keep our eye on a “mesoscale convective complex” that likely develops later today over the Upper Midwest which could head in our direction by early tomorrow. Looking ahead, a cold front appears destined to push through the region by the weekend bringing more comfortable temperatures back to the area.

High pressure expanded into the Mid-Atlantic region on Thursday and it stays close enough today to provide us with more sunshine and comfortable temperatures. The weather, however, gets more unsettled as we get into the weekend as weak low pressure systems will push in this direction on each day. As a result, a few showers are possible on Saturday although the day will not be a washout and it’ll be a bit cooler. Sunday should turn a bit warmer and there is the threat of showers and maybe a couple of thunderstorms. High pressure resumes control across the NE US on Monday and there should be plenty of sunshine during the first half of next week with temperatures in the 80’s. At the same time, much of the southern US will undergo a big-time heat wave.
